Pretty much everything - Java is reasonably fast, reasonably safe, and reasonably expressive. I wouldn't call it the best at any of those things. The real advantage to me is that the virtual machine is ubiquitous and many people can understand it. Since I have the most experience in this language, it's my tool of choice for most projects.

I've also been learning JavaFx so that I can build user interfaces without the web. I've started several single-page-application projects that worked, but felt like workarounds or hacks and would be better-served as self-contained applications.

Do I really need to explain? Well to me, the most appealing factor in Java besides the unbelievable community and vast array of available libraries, is just the amount of effort that has been put in the modern JVM. Decades of optimization and improvements have lead to a terrific piece of technology. I admire the people contributed to that.

Shouldn't surprise anyone, as minecraft is also java-based. Java is used for much more than just the plugins though. JCVortex (our API) is also served with vert.x (Java) and many of our team-internal tools also originated from java or are still java-applications.

The most popular language in the world, definitely every programmer would use the Java language at some point. Frankly, I only use java when it’s a must. I find the language to be a little bit tedious when working with it.

bytelore.com makes extensive use of Java in its applications. We use Java due to its performance, community and the number of other projects built in the language. We have many projects and libraries built in Java.

The whole backend part (deployment and other scripts, business logic, web interface) is written in Perl.

Весь бэкенд (скрипты деплоя и прочие, бизнес-логика, веб-интерфейс) написан на Perl.

I use Perl to rip through log files and compare them to some signature files I have created. When I get a match, it adds the bad guy to the list of shame in MySQL.

I have been study with videos and tutorials

Backend logic (REST, Auth0, Redis, Postgres, functional graph library (fgl), ...)

A very expressive language, lets you say the same thing in many different ways

Our internal deployment tool, called Mordor, is written in Haskell.

We use perl with rex to control our distributed systems.

Still experimental work for multikernel OS.

I use perl on some legacy applications.

Don't worry, be type-safe.
